Bessie Ho - a very happy Gelair Health-e Split user - talks about how Gelair Health-e Split helped her mom when her mom stayed in her grandfather's old house - and it's full of black moulds after years of not being stayed in. Her mom used bleach and vinegar and didn't help the situation, then finally tried Gelair Health-e Split and it helped. Her mom even brought a few packs back with her to Canada!
